Btraighl pedicellariae, like those of the type, measure about 0.28 mm., while the 

 adambulacral measure 0.25 mm. 



Those specimens have the characteristic heavy apical oral spine, each angle 

 pan- with a small companion at each side. Tho first 9 or 10 adambulacrals are 

 mostly monacanthid, the rest alternating monacanthid and diplacanthid. There is a 

 Binglerow of actinal spines extending about half the length of the rays and the carinal 

 spines are conspicuously heavier than the dorsolaterals. Both sorts are ^cylindri- 

 cal, not long, with rounded very finely striate tips. The coarsely striated madre- 

 porite is slightly adcentral to the middle of r. 



The type of L. coei was taken in Berg Bay, 10 fathoms, and is figured by Verrill 

 (1914) on Plate 17, Figure 1; the cotype of Orthasterias merriami was taken in 10 

 fathoms, Berg Bay (it is labeled "Berg Bay, Glacier Bay"). Another smaller speci- 

 men of coei is figured as the type on Plate 9, Figure 1, and as cotype on Plate 

 17, Figure 2. Unfortunately, neither specimen of coei can be found in the Yale 

 Museum. 



I think L. coei, the type of which measured only R 30 mm., is undoubtedly a 

 young form of the cotype of 0. merriami. The cotype of merriami seems not dis- 

 tinguishable specifically from the type (from off Juneau, Alaska, 20 fathoms). If the 

 types of coei are really lost, as seems probable, the species will have to rest upon the 

 type of merriami. The name coei has page priority over merriami. 



Type. — Yale Museum (probably lost). 



Type locality.— Berg Bay (Glacier Bay), Alaska, 10 fathoms (Harriman Alaska 

 expedition). 



Distribution. — Juneau to Shelikof Strait, Alaska, 10 to 102 fathoms. 



Specimens examined.— OS Juneau, 20 fathoms (type of merriami). Berg Bay, 

 Glacier Bay, 10 fathoms (paratype of merriami). Station 4292, Shelikof Strait, 94 

 to 102 fathoms, blue mud, fine sand, bottom temperature 39.8° F. (three specimens). 



LEPTASTERIAS COEI TRUCULENTA, new subspecies 



Plate 24, Figure 3; Plate 25; Plate 26; Plate 29, Figures 1, 2, 4 



Diagnosis. — Rays six; size large; in general appearance similar to L. coei (adult) 

 but with more numerous abactinal spines, on the average longer; without conspicuous 

 interspinal clusters of crossed pedicellariae, either alone or surrounding small second- 

 ary spinelets (these having developed into primary spines); with numerous very large 

 abactinal, intermarginal, and actinal straight pedicellariae, having oblong to squarish 

 coarsely toothed jaws, in addition to smaller compressed ovate ones; abactinal spines 

 finely to coarsely fluted. Rays long, rather slender, arched in alcoholic specimens; 

 disk small; interbrachial angles very sharp; skeleton well covered by opaque skin, 

 and abactinal spines with a thick pad of pedicellariae which in alcoholic specimens 

 frequently touches that of neighboring spines; spines upright bristling, rather uni- 

 formly spaced, robust, the abactinal without definite serial order, but the marginals 

 and actinals (one to three series) in regular, rather close series. R 220 to 225 mm., 

 r 30 mm., R=7.3 r; breadth of ray at base 30 mm. (type). R 121 mm., r 19 mm., 

 R = 6.3 r; breadth of ray at base 20 mm.; station 4777.
